Ohmahgerd, I can post in here now!
I knew that Swampland was going to be my favorite map before I even got my hands on it (I love jungle levels), but tree hopping across the entire map is so much fun that I ended up doing so for a couple minutes straight the first time I loaded it up, much to the dismay of my objective-oriented teammates.
Wargames and Runoff didn't stand out to me in the same way Swampland did (except for the intro to Wargames; Respawn should make more map-unique intros!), but they're still great maps that fit right into the original 15 map lineup.
Has anyone encountered any of the new maps in any of the playlists other than the Expedition Variety one?
I ran into Wargames once when playing Attrition after I got sick of playing Pilot Hunter + LTS over and over in the variety playlist.
According to Respawn, they should also be in Hardpoint. My big question is how the game deals with the have/have-nots in Attrition/Hardpoint; mainly, can a person without the DLC get thrown into a lobby where everyone else has it, thus binding everyone in that lobby to the base 15 maps? If so, are the DLC owners subsequently aware that no DLC maps will come up in that lobby's rotation? I'd expect that the Attrition/Hardpoint playlists aren't distinguishing between the two groups, but I haven't seen anything definitive.
